PURPOSE: In vitro sonography of lymph nodes was performed to ascertain the differential point between benignancy and malignancy. MATERIALS AND METHODS: Ninty-one lymph nodes were obtained at gastric cancer surgery and pathologically proved as benignancy in 68 and malignancy in 23 cases. Sohographic and pathologic correlation of resected ninty one lymph nodes was done in terms of size, the ratio of longest diameter versus shortest diameter, central hyperechogenicity, and peripheral cortical echo. RESULTS: Sonographic findings of benign lymph node were small size, oval shape(85%), narrow central high echogenicity(44%), and symmetric cortical thickening(41%). Sonographic findings of malignant lymph node were large size, round contour(39%), loss of central high echogenicity(82%), and diffuse increase of cortical thickness(82%). CONCLUSION: The most reliable sonographic criterion for differentiation of benignancy from malignancy was size of a lymphnode.

Epidermal growth factor receptor (EGFR) is an intergral membrane protein. Overexpression or mutation of EGFR may play a role in careinogenesis. Recently, many molecular biologic techniques have been used to study expression of oncogenes. One of them, in situ mRNA hybridization, using paraffin embedded blocks, offers a unique means to allow precise localization within histological preparations, and also overcomes problems relating to translation defects and abnormal translation. In order to confirm the usefulness of epidermal growth factor receptor as a tumor marker, and to compare the expression of EGFR between in situ MRNA hybridization and an immunohistochemical study, in situ MRNA hybridization was performed along with an immunohistochemical study for EGFR in paraffin sections of 84 uterine cervix carcinomas. A positive reaction for EGFR was observed mairdy in the cytoplasm of tumor cells. The vascular muscle layer and uterine muscle tissue around the cancer nest revealed a positive reaction in immunohistochemical stain for EGFR, with a negative reaction for EGFR mRNA. In the cancer nests, the immunohistochemical positive reaction for EGFR was strong in differentiated cells and keratin pearls, but a strong positive reaction for EGFR mRNA was localized in undifferentiated cells. The overall positive of immunostaing for EGFR was 77% for uterine cervix carcinoma; 71 % for carcinoma in situ, 71 % for microinvaseve carcinoma, and 89% for invasive carcinoma. The overall positivity of EGFR from in situ MRNA hybridization was 94% of the uterine cervix carcinoma; 93% for carcinoma in situ, 93% for microinvasive carcinoma, and 96% for invasive carcinoma. From these results, EGFR is a useful tumor marker for uterine cervix carcinoma, and in situ mRNA hybridization has greater sensitivity and specificity than immunohistochemistry.

OBJECTIVE: The purpose of this study is to investigate the effect of chronic deprivation of estradiol on the serotonin level in Sprague-Dawley rat's cerebral cortex and hippocampus. METHODS: One hundred of female Sprague-Dawley rats were taken care for seven to eight weeks, then they were randomly assigned into two group; fifty rats underwent bilateral oophorectomy & the remaining rats were the control group. Six months after oophorectomy, brain tissue was extracted from cerebral cortex and hippocampus and then homogenated: this was done in the both groups. The upper layer of the homogenated substance was taken and frozen and finally dried up. The next process was marking with PITC, quantification through HPLC and comparing with authentic serotonin. Protein quantity was measured by using Bradford method. RESULTS: Comparison between the bilateral oophorectomy group and the control group for serotonin content in the cerebral cortex was 134.2+/-14.3 nmol/mg protein(mean+/-SEM) and 122.5+/-11.6 nmol/mg protein in each group. As for the serotonin content in the hippocampus was 148.8+/-13.9 nmol/mg protein and 132.9+/-13.7 nmol/mg protein in each group. It shows that, there was no significant difference in the serotonin level, in the two areas mentioned above. CONCLUSION: The effect of estradiol on the serotonin level may be dependent on the hormonal change duration. Chronic effect of hypoestrogenism might have no effect on tryptophan hydroxylase and monoamine oxidase, thus not changin the serotonin level. These data supported the previous findings that chronic hypoestrogenism had no effect on serotonin level.

Adenoid cystic carcinoma arising from the submucosal glands of the trachea and bronchial tree is rare. The histopathology and natural history of bronchial adenoid cystic carcinoma have been well documented, but detailed descriptions of its cytomorphology are few. We report a case of primary bronchial adenoid cystic carcinoma in a 20-year-old female, diagnosed by bronchial brushing cytology. The cytologic specimens showed large clusters of small cells arranged around cystlike spaces containing globular basophilic material.

This study was a descriptive research in search of a nursing intervention scheme to improve stroke patients' quality of life by understanding the relationship of stroke patients' ADL. depression, self-efficacy and quality of life with various variables and identifying factors that affect their quality of life. Each subject was interviewed one to one based on a structured questionnaire. With regard to research tools, Modified Barthel Index (MBI: Fortinsky et al., 1981), which was translated by Choi, Hye-sook (996), was used in measuring ADL, Randloff's (1977) tool. which was translated by Choi, Soon-hee, was used in measuring depression, and the tool developed by Sherer et al. (1982), which is to measures self-efficacy under general conditions not limited to specific conditions, and modified by O, Bok-ja (1994) was used in measuring self-efficacy. The quality of life was measured using the scale of satisfaction of life developed by Diener et al.(1985). The results of this study were as follows: 1. The means of ADL of the subjects was 79.5+/-1.9, depression 26.8+/-0.4. self-efficacy 47.1+/-5.7, and the quality of life 12.3+/-.9. 2. The subjects' quality of life showed a statistically significant difference according to gender (t=7.9, p= .006), satisfaction with income (F= 5.8, p = .004), the burden of medical fee (F=3.7, p= .028) and the period of disease (F=2.8. p= .042). 3. With regard to relationship among ADL, depression, self-efficacy and the quality of life, ADL was in a relatively low positive correlation (r= .293, p= .003) with and the quality of life, depression in a high negative correlation (r=- .634. p= .000) with the quality of life. and self-efficacy in a positive correlation with the quality of life (r= .388. p= .000). 4. Factors that made a significant influence on the quality of life were depression (8=- .309. p= .001) and satisfaction with income (8=-2.611. p= .001). Based on these results, this study made following suggestions: 1. It is necessary to run rehabilitation programs to improve stroke patients' ADL, depression and self-efficacy. 2. It is necessary to perform research of monitoring stroke patients' quality of life in various areas using measuring tools.

PURPOSE: The study was to examine the effects of the individual education about chemotherapy for cancer patients as well as their family who are receiving the first chemotherapy on self-care knowledge, self-care performance, family support, and anxiety level. METHODS: A non-equivalent control group was used in this interventional study. A total of 50 patients with cancer aged above 19 in the K university hospital, Seoul, Korea, participated in the study (Experimental group: n=25, Control group: n=25). The education about chemotherapy was offered one week after hospital discharge, which was followed by telephone counseling Data were analyzed by the SPSS/WIN 20.0 program using percentage, frequency, mean, standard deviation, x2 test, and independent t-test. RESULTS: The experimental group showed a significantly better self-care knowledge (t=4.094, p < .001), self-care performance (t=3.532, p=001), family support (t=2.170, p=.035), and anxiety control (t=4.780, p < .001) than the control group. CONCLUSION: The findings suggest that the individual education should be considered for cancer patients and their family in the clinical fields.

PURPOSE: This study was performed to evaluate prognostic significance of Rb and p53 protein immunostaining in renal cell carcinoma. We investigated correlations between Rb, p53 immunostaining and nuclear grade and stage as prognostic factors of renal cell carcinoma. MATERIALS AND METHODS: Subjects of this study were sixty-nine cases of renal cell carcinoma. We used indirect immunohistochemical methods in the formalin-fixed paraffin- embedded tissue (Rb: Pharmingen, USA; p53: Novocastra, UK). In staging and nuclear grading of the renal cell carcinoma, the American Joint Commitee on Cancer (AJCC) TNM system and Fuhrmans grading system were applied respectively. RESULTS: According to Fuhrmans grading system, four cases were classified grade I, 15 cases were classified grade II, 13 cases were classified grade III, and 37 cases were classified grade IV. By AJCC TNM staging system, 29 cases were grouped stage I, 20 cases were grouped stage II, 15 cases were grouped stage III and five cases were grouped stage IV. In 55 cases (79% of all cases), Rb protein was expressed. Expression of Rb protein did not correlate with nuclear grade nor tumor stage. p53 protein was expressed in 17 cases (24% of all cases). p53 protein expression was frequently detected in high nuclear grade group (p < 0.05), but was not correlated with tumor stage. CONCLUSION: Expression of Rb protein was not conelated with nuclear grade and stage. And expression of p53 protein was not correlated with stage, but it is correlated with nuclear grade. Thus immunohistochemical examinstion of p53 could be a histological prognostic factor.

PURPOSE: The purpose of this study was to investigate the present status of falls among inpatients in general hospitals and to identify the fall risk factors that reflect the characteristics of domestic hospitals. METHODS: Data were collected between December 15, 2016 and January 15, 2017 from 32 Korean hospitals having 500 or more beds. First, 42 risk factors were extracted based on literature review and expert opinions. Then the importance of each factor was evaluated by 223 nurses from medical and surgical adult ward and intensive care units in 40 hospitals. RESULTS: The incidence rate of falls in 18 hospitals was 3.87 per 1,000 total discharged patients and 0.55 per 1,000 patient-days, and the rate of injury-related falls was 40.5%. Major risk factors for falling were identified as the following: being over 65 years of age, history of falls during admission, physical mobility disorders requiring assistance, physical factors (dizziness or vertigo, unstable gait, general weakness, walking aids, visual problems), cognitive factors (delirium, lack of understanding on limitations), neurological disease, CNS medications CONCLUSION: The findings provide information that can be in the development of a fall risk assessment tool for inpatients in general hospitals in Korea.
